311 Tunnel protection directly associates an SA with all packets
312 ingress and egress on the tunnel. This could also be achieved by
313 assigning an SPD to the tunnel, but that would incur an unnessccary
316 For tunnels the ESP acts on the post-encapsulated packet. So if this
321 where O-IP is the overlay IP addrees that was routed into the tunnel,
322 the resulting encapsulated packet will be:
323 +---------+------+------+
324 | Payload | O-IP | T-IP |
325 +---------+------+------+
326 where T-IP is the tunnel's src.dst IP addresses.
327 If the SAs used for protection are in transport mode then the ESP is
328 inserted before T-IP, i.e.:
329 +---------+------+-----+------+
330 | Payload | O-IP | ESP | T-IP |
331 +---------+------+-----+------+
332 If the SAs used for protection are in tunnel mode then another
333 encapsulation occurs, i.e.:
334 +---------+------+------+-----+------+
335 | Payload | O-IP | T-IP | ESP | C-IP |
336 +---------+------+------+-----+------+
337 where C-IP are the crypto endpoint IP addresses defined as the tunnel
